Estimate voltage drop (V/% ) from voltage, current, distance, and conductor settings. Pass/Warn is a reference only. Selecting a standard set lists candidate cable sizes by voltage drop.
Basic conditions
Conductor length used in calculation:
Conductor conditions
Used for resistance temperature correction (reference). Defaults to 20℃ if empty.
Simplified formula corrects resistive drop by cosφ (reactance not included).

Reference: approximated from resistivity and cross-sectional area.
Allowable reference (Pass/Warn only)
Allowable values must follow regulations and design documents (shown for reference only).
